What To Know
- It assigns a numerical value from 1 (softest) to 10 (hardest) based on a gemstone’s ability to scratch or be scratched by other materials.
- However, it is not as hard as other popular gemstones like ruby and sapphire, both of which have a hardness of 9.
- Diamond, the epitome of hardness in the gemstone world, sits at the top of the Mohs scale with a perfect 10.
When it comes to gemstones, two of the most coveted and well-known are tanzanite and diamond. Both possess unique beauty and distinct properties, captivating the hearts of jewelry enthusiasts worldwide. One question that often arises is, “Is tanzanite harder than diamond?” This blog post delves into the intriguing world of these gemstones, exploring their hardness, durability, and other fascinating characteristics. Join us as we unveil the secrets behind these precious stones and discover the truth about their comparative hardness.
Understanding Hardness:
Hardness is a crucial property of gemstones, determining their resistance to scratching and wear. The Mohs scale, developed by German mineralogist Friedrich Mohs in 1812, is the standard for measuring hardness. It assigns a numerical value from 1 (softest) to 10 (hardest) based on a gemstone’s ability to scratch or be scratched by other materials.
Tanzanite’s Hardness:
Tanzanite, a mesmerizing blue-violet gemstone, ranks 6.5 to 7 on the Mohs scale. This indicates that it is harder than many common minerals, such as quartz (hardness 7) and feldspar (hardness 6). However, it is not as hard as other popular gemstones like ruby and sapphire, both of which have a hardness of 9.
Diamond’s Hardness:
Diamond, the epitome of hardness in the gemstone world, sits at the top of the Mohs scale with a perfect 10. This means that it is the hardest naturally occurring mineral on Earth. Diamonds’ exceptional hardness makes them highly resistant to scratching and abrasion, contributing to their durability and longevity.
Comparative Hardness:
Comparing the hardness of tanzanite and diamond, it is evident that diamond is significantly harder. With a Mohs hardness of 10, diamond is nearly four times harder than tanzanite. This means that diamond can easily scratch tanzanite, while the reverse is not true.
Implications for Jewelry:
The difference in hardness between tanzanite and diamond has implications for jewelry design and care. Tanzanite’s lower hardness makes it more susceptible to scratches and damage, especially when worn in everyday settings. Therefore, it is essential to handle tanzanite jewelry with care and avoid exposing it to rough surfaces or activities that could cause abrasion.
Other Gemstone Properties:
While hardness is a crucial factor, other gemstone properties also contribute to their value and desirability. These properties include:
- Color: Tanzanite’s captivating blue-violet hue is its defining characteristic, while diamonds are renowned for their colorless transparency.
- Clarity: Both tanzanite and diamonds can exhibit inclusions, which are natural imperfections that affect their clarity. Generally, gemstones with fewer inclusions are considered more valuable.
- Carat Weight: The size of a gemstone is measured in carats, with one carat equaling 200 milligrams. Larger gemstones are typically more valuable, although rarity and other factors also influence their worth.
Recommendations:
Tanzanite and diamond are two extraordinary gemstones with unique properties and captivating beauty. While diamond reigns supreme in terms of hardness, tanzanite possesses its own allure with its vibrant color and distinct characteristics. Whether you prefer the brilliance of diamond or the enchanting blue of tanzanite, both gemstones offer timeless elegance and enduring value.
Basics You Wanted To Know
1. Why is diamond harder than tanzanite?
Diamond’s hardness is attributed to its atomic structure, specifically the strong covalent bonds between its carbon atoms. These bonds form a rigid lattice that resists deformation and scratching.
2. Can tanzanite scratch glass?
Yes, tanzanite can scratch glass because it has a higher hardness (6.5 to 7 on the Mohs scale) than glass (5.5). However, it is important to note that tanzanite is still relatively soft compared to other gemstones and can be scratched by harder materials.
3. Which gemstone is more durable, tanzanite or diamond?
Diamond is more durable than tanzanite due to its exceptional hardness. Diamonds are highly resistant to scratching, abrasion, and wear, making them ideal for everyday wear and jewelry applications.
4. How should I care for tanzanite jewelry to prevent scratching?
To care for tanzanite jewelry and prevent scratching, it is essential to:
- Store tanzanite jewelry separately from other gemstones to avoid accidental scratching.
- Avoid wearing tanzanite jewelry during activities that could cause abrasion, such as gardening or sports.
- Clean tanzanite jewelry gently with a soft cloth and mild detergent. Avoid using harsh chemicals or ultrasonic cleaners.
5. Can I wear tanzanite and diamond jewelry together?
While it is possible to wear tanzanite and diamond jewelry together, it is important to be cautious to prevent scratching. Diamonds are harder than tanzanite, so it is best to avoid direct contact between the two gemstones.
